Details of the NASA sponsored General Electric Energy Efficient Engine (E3) technology program are presented along with a description of the engine, cycle and aircraft system benefits. Opportunities for further performance improvement beyond E3 are examined. Studies leading to the selection of the E3 cycle and configuration are summarized. The advanced technology features, cycle and component performance levels are also presented. An evaluation of the benefits of the fully developed Flight Propulsion System (FPS) is made relative to the NASA program goals by comparing the FPS with the CF6-50C where both are installed in advanced subsonic transport aircraft. Results indicate that a mission fuel saving from 15 to 23 percent is possible depending on mission length.

The Garrett GTCP36-300 Series Auxiliary Power Unit is being developed for use on advanced technology transport aircraft in the 150-passenger size class. The first application will be the Airbus Industries A320 Aircraft. The APU uses a 6:1 pressure ratio, single-stage compressor and turbine, driving a single-stage load compressor and accessory gearbox. The 480 horsepower APU delivers compressed air to the aircraft pneumatic system and drives a customer furnished 90 kva, 24,000 rpm electrical generator. State-of-the-art aerodynamics, materials, and digital electronics are used to give the user-airlines an APU delivering maximum performance with minimum envelope, weight, and cost of ownership.

Based on airline pilot surveys, industry committees and workshops, conducted on advanced technology “glass cockpit” airplanes, concerns have been raised about the application and long-term effects of automation technologies. It has been pointed out that purely technology-driven designs had resulted in unintended and unforeseen negative consequences. In order to counter this trend it has been proposed to shift the focus from technology-centered designs to what has become known as human-centered design. There are three primary objectives within a human-centered design philosophy: (1) the design should enhance the user's abilities, (2) the design should help overcome user limitations, and (3) the design should foster user acceptance. This paper discusses the human-centered design objectives within the context of commercial transport airplane developments. Representative examples of a human-centered design are presented.
